Most hemorrhoids do not go away on their own after they grow out, and they need to be treated accordingly according to the specific individual situation and symptoms. Asymptomatic hemorrhoids do not require treatment, and symptomatic hemorrhoids do not need to be cured, so conservative treatment and non-surgical treatment are the main indications for surgery. For internal hemorrhoids, generally Ⅲ degree and Ⅳ degree internal hemorrhoids are indications for surgery. For inflammatory external hemorrhoids, thrombosed external hemorrhoids and connective tissue external hemorrhoids, the decision is based on the patient’s main clinical symptoms, and the following cases require surgery: 1. Frequent fecal bleeding, frequent episodes, very large amount of blood in the stool, or even anemia affecting the general body function, and the effect of conservative treatment is not obvious. 2. Large hemorrhoid nucleus, the degree of prolapse is more serious, after the stool or walking out of the anus can not be returned by themselves, and after the hand return, it is again prolapsed. The hemorrhoids are large, often inflamed, swollen and painful.
